Abstract

Mixtures based on vinyl chloride polymers and small amounts of a copolymer of an ester of acrylic acid or methacrylic acid. The said copolymer contains acrylic acid ester or methacrylic acid ester units, units which contain a lactone ring structure, and, optionally, units of other copolymerizable monomers. The mixtures exhibit improved processability and may in particular be used for the manufacture of films, sheets and the like.
